During the 1960s, when it became apparent that the stone would be submerged by the rising waters of Lake Diefenbaker, efforts were made to save the mistasiniy. A long campaign led by the late Zenon S. Pohorecky, a professor of anthropology and archaeology at the University of Saskatchewan, to move the rock to higher ground ultimately proved unsuccessful. Many believe a “quiet” decision was made to quell the lobby: on the morning of December 1, 1966, a crew from the PFRA (Prairie Farm Rehabilitation Administration) arrived with a reported 60 sticks of dynamite and reduced the millennia-old stone to rubble. Fragments were later incorporated into a cairn at Elbow Harbour and a memorial to Chief Poundmaker on the Poundmaker Cree Nation reserve in the Cut Knife area. The remainder now lies submerged. With the advent of Lake Diefenbaker as a recreation area, the present resort village, incorporated on August 1, 1980, began to develop. Today, the community of Mistusinne has 247 privately-owned properties, the majority for seasonal use, as well as a nine-hole golf course, a boat launch, and miles of sandy beach. Other than the golf course, there are no commercial developments at Mistusinne; the nearby village of Elbow offers a range of goods and services. The above population figure is that of the permanent, year-round residents; the number is many times higher during the peak summer months. Mistusinne is situated in the RM of Maple Bush No. 224.
